An electronic device has a first case which houses a part of a liquid cooling system and mounted components, and a second case which houses the other part of the liquid cooling system. In one example, the second case houses and a display unit. In an all-in-one computer example, the second case may serve as the access lid. In the electronic device, the liquid cooling system has a pump which feeds cooling liquids a heat block which receives heat from an electronic component, a pipe which transfers heat from the liquid to a heat sink, and a tube which connects these parts with one another. The first case has a first board mounted with the electronic component over a part of the liquid cooling system. Methods of manufacturing electronic devices with such cooling systems also are disclosed.

Electric device with liquid cooling system and method of manufacturing thereof

An electronic device capable of preventing air from entering a pump for circulating a cooling medium is provided in a small-sized electronic computer provided with a liquid cooling system, which has a liquid cooling construction for circulating a cooling liquid with the use of a power source and for cooling a high temperature part of with the cooling liquid. The electronic device of the invention comprises a gas entering preventing mechanism provided in a part of a circulating path, through which the cooling liquid circulates, to prevent air from entering the power source.
